Questions & Answers about System Three Wood Flour Filler:

2014-04-27DOMINIC CARPENTER asked:Can I use wood flour with system Three T-88 Epoxy?

+Expand Answers

2014-04-27HOWARD SPRUIT:I have never used wood flower with T-88
I use the wood flower to thicken the standard system three glop, to make it thicker and to fill large gaps that do not require maximum strength. My experience with T-88 is that it is already thick, so you would not need to much wood flower to thicken it.
System 3 used to have a tech. assist department so ask them what they think

2014-04-28GREG GRUNDTISCH:You can use it in most any epoxy, but t-88 is already thickened and shouldn't need more. The more flower you add the weaker the epoxy becomes. I sometimes use it to color the epoxy brown. For strength, cabosil or micro fibers and the like, are better. I use flour mostly for filling gaps and holes, and fillets, where tape and epoxy are over it.

2013-01-25MIKE BIRKE:Sure will. No problem. Once it's mixed with epoxy, and it cures, you can almost treat it like JB Weld.

2013-01-25MARK WAKEFORD:Hello Alfred:
I can't say I have any experience with "brain cavities". However, I did use use this wood filler for filling cracks and holes in wood prior to finishing. The only trick is to decide what kind of glue you want to use. I used a 2 part clear Epoxy(extended set), which I mixed the wood filler into (would be expensive for large projects such as yours). The resulting hardened mixture was so much harder than wood. As far as screws, you would need to pre-drill your holes as I doubt you would be able to self-drill a regular wood screw( and I am not fond of self-drilling screws in wood as it tends to rip out the wood and cause a poor grip). You can also consider Auto body Bondo( 2 part) if color is not important, this would cost considerably less than Epoxy( yet not as strong and hard, but more than sufficient for your mounts). As you may know the typical adhesive used for this filler is casein wood glue(very cheap). You can experiment with this and see if it would be strong enough for your mounts( I think it would, but large areas would take several days to cure and there would be some shrink back as casein glues are water based). If I was you, I would forget the wood filler and just use the Auto body Bondo ( much, much cheaper).

2013-01-26JERRY A. OLSON:I don't know the answer to that. I would mix some wood flour with epoxy and let it set up in a sample mass. Then I would drill and screw it to see if it would hold.

2013-01-26SANTO SANTORIELLO:If used to thicken epoxy, it can be drilled and tapped to accept screws.
This is often done in boat construction.

Mix until the consistency of "peanut butter" and apply; make sure the mixture is thick enough, otherwise it will run. Tricks for application: use tongue depressors to create a smooth fillet, and a credit/hotel card to scrape away the excess material. I used this product for filleting a new interior to my 1965 Columbia Contender. I recommend using this product with Jamestown's one-pump epoxy/hardener system, it worked like a charm! I'm finishing the fillet work, about about 1/2 way through this bucket, it is more than enough for a 24' boat interior.

Mix epoxy thouroughly prior to adding wood flour. Then add and mix small amounts and continue mixing until the desired consistancy is reached. Be sure to coat surfaces with mixed resin alone to prevent a starved joint. Sanding will take a bit of effort but it fairs pretty well.

I found it to mix easily with west system epoxy, and worked well for thickening epoxy for fillets, gap filling and etc. Sands much more easily than colloidal silica when that level of strength is not paramount. It mixes up and dries to an unpleasant brown color, so don't plan to leave it barem, and clean as you go. I have not drilled it, and don't know how well it performs in holding screws. I would probably use colloidal silica in the instance of any structural fastener support, etc.....

Wood filler is used to thicken epoxy for gluing and filleting. I find this product mixes better than others that I have tried. It is preferable to sanding dust which is just too coarse. It has adequate strength for gluing purposes.
